Instant-Grid is a Knoppix-based live-CD bundled with a pre-configured grid-environment based on the Globus-Toolkit. One PC started from this CD becomes the Instant-Grid frontend. It also functions as a PXE boot-server, allowing further PC in the same local network to boot the Instant-Grid-environment via network-interface-card. Together with the frontend these PC automatically form a working test-grid. Like with the original Knoppix, the existing configuration of the participating PC is not touched (except maybe for enabling the PXE boot-option), and remains instantly available by a simple reboot. Instant-Grid is under development. A non-beta version 1.0 is expected to be available in late autumn 2007.
